e764ed31f6 Eval cache: fix cache regressions 
- Fix eval cache not being persisted in `nix develop` (since #10570)
- Don't attempt to commit cache transaction if there is no active transaction, which will spew errors in edge cases
- Drive-by: trivial typo fix

3fc77f281e No global settings in libnixfetchers and libnixflake 
Progress on #5638

There are still a global fetcher and eval settings, but they are pushed
down into `libnixcmd`, which is a lot less bad a place for this sort of
thing.

Continuing process pioneered in
52bfccf8d8.

09763c7cad getDerivations: add attributes to trace 
This improves the error message of nix-env -qa, among others, which
is crucial for understanding some ofborg eval error reports, such as
https://gist.github.com/GrahamcOfBorg/89101ca9c2c855d288178f1d3c78efef

After this change, it will report the same trace, but also start with

9b88bf8adf Fix underflow in Printer::printAttrs 
The code that counts the number of elided attrs incorrectly used the
per-printer "global" attribute counter instead of a counter that
was relevant only to the current attribute set.

This bug flew under the radar because often the attribute sets aren't
nested, not big enough, or we wouldn't pay attention to the numbers.
I've noticed the issue because the difference underflowed.

Although this behavior is tested by the functional test
lang/eval-fail-bad-string-interpolation-4.nix, the underflow slipped
through review. A simpler reproducer would be as follows, but I
haven't added it to the test suite to keep it simple and marginally
faster.

```
$ nix run nix/2.23.1 -- eval --expr '"" + (let v = { a = { a = 1; b = 2; c = 1; d = 1; e = 1; f = 1; g = 1; h = 1; }; b = { a = 1; b = 1; c = 1; }; }; in builtins.deepSeq v v)'

b51e161af5 Cleanup ContentAddressMethod to match docs 
The old `std::variant` is bad because we aren't adding a new case to
`FileIngestionMethod` so much as we are defining a separate concept ---
store object content addressing rather than file system object content
addressing. As such, it is more correct to just create a fresh
enumeration.

This fixes an inaccuracy in cc6f315252,
in the update to Nixpkgs 24.05 https://github.com/NixOS/nix/pull/10835

After this fixup, the build log won't ask for an upgrade, and we'll be
able to collect when a coroutine exists, e.g. during filterSource.

cc6f315252 nix: Disable GC during coroutine when bdwgc < 8.4 
This re-enables support for older bwdgc versions without complicating
the code too much.
Coroutines generally only interfere with GC during source filtering,
so it's not too bad of a regression on older bdwgc.
This seems preferable over conditional compilation to enable the patch
etc; we've already spent a lot of complexity budget on this GC-coroutine
interaction...

Robert Hensing
2477e4e3b8 libexpr: Use GC_set_sp_corrector instead of patch 
Manually tested by printing to stderr in both branches (sp in os
stack, or not), and triggering a GC in a filterSource function,
e.g.:

    let
      generateTree = n: if n == 0 then "ha" else { left = generateTree (n - 1); right = generateTree (n - 1); };
    in
      builtins.deepSeq (generateTree 18) ...

Note that the darwin still uses the strategy of disabling GC, despite
having an implementation that compiles. The proper solution will be
enabled and tested later.

473d2d56fc Remove 100s of CPU time (10%) from build times (1465s -> 1302s) 
Result's from Mic92's framework 13th Gen Intel Core i7-1360P:

Before: 3595.92s user 183.01s system 1360% cpu 4:37.74 total
After: 3486.07s user 168.93s system 1354% cpu 4:29.79 total

I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.

* docs: mention importNative/exec in allow-unsafe-native-code-during-evaluation

Both of these still needs their own actual documentation, but they are
at least now mentioned that they exist and what they're enabled by.

In addition:

- Take the opportunity to add a bunch more missing hyperlinks, too.

- Remove some glossary entries that are now subsumed by dedicated pages.
  We used to not be able to do this without breaking link fragments, but
  now we can, so pick up where we left off.

081faeda8c Forbid drvPath in strictDerivation outputs attribute 
builtins.strictDerivation returns an attribute set with drvPath and
output paths. For some reason, current implementation forbids drv
instead of drvPath.

d641e8f717 builtin:fetchurl: Revert impureEnvVars attribute 
This was changed in #10611, which caused the derivation paths of
anything using builtin:fetchurl to change (i.e. all of
Nixpkgs). However, impureEnvVars doesn't actually do anything for
builtin:fetchurl, so we can just set it to its historical value.

ba5929c7be Merge InputAccessor into SourceAccessor 
After the removal of the InputAccessor::fetchToStore() method, the
only remaining functionality in InputAccessor was `fingerprint` and
`getLastModified()`, and there is no reason to keep those in a
separate class.

f34b52b521 libexpr: Add missing GC root for baseEnv 
This missing GC root wasn't much of a problem before, because the
heap would end up with a reference to the `baseEnv` pretty soon,
but when unit testing, the construction of `EvalState` doesn't
necessarily happen well before GC runs for the first time.
